Questions & Answers

Q: What are the three bones present in the shoulder region?

The three bones present in the shoulder region are collar bones, shoulder blade, and upper arm bone. They provide flexibility and facilitate movement in the shoulder.

Q: How do the collar bones, shoulder blade, and upper arm bone contribute to body movements?

The collar bones, shoulder blade, and upper arm bone together form the shoulder joint. The collar bones connect the shoulder to the breastbone, the shoulder blade acts as the socket, and the upper arm bone acts as the ball. This ball-and-socket joint allows for rotating and moving the entire arm.

Q: What is the significance of pelvic bones in the body?

Pelvic bones are located in the pelvis region, which lies between the abdomen and thighs. They support the abdomen and thighs and play a crucial role in sitting postures. They also include parts of the backbone and hip bones.

Q: How do the pelvic bones contribute to sitting postures?

When we sit, our weight and pressure are exerted on the pelvic bones. These bones provide stability and support, making it possible to maintain a seated position comfortably.

Summary & Key Takeaways

• The shoulder region consists of three bones: collar bones, shoulder blade, and upper arm bone, which together allow for movement and flexibility.

• The shoulder joint is a ball-and-socket joint, where the rounded upper arm bone fits into the socket of the shoulder blade.

• The pelvis region includes the pelvic bones, which support the abdomen and thighs and play a role in sitting postures.
